ABSTRACT
Ni-Fe phosphide electrodes with tunable Fe content were developed for neutralization-assisted hydrogen production by forward-bias bipolar membrane water electrolysis (BPMWE-f), achieving overpotentials of 80 mV for acidic HER and 222 mV for alkaline OER and a cell voltage of only 0.94 V at 10 mA cm-2.
